TIRE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. I759,134, dated May 3,1904.

Application filed November' 29, 1901. Serial No. 84,056. (No model.)

0 ft2/Z 'LU/tom it may concern:

Be it known that l, JOHN I-I. ScI-IoLDINe, a citizen of the UnitedStates of America, and a resident of Yonkers, in the county ofWestchester and State of New York, have invented certain new and usefulImprovements in Tires for Vehicles, of which the following' is aspeciiication.

This invention relatos rto tires for vehicles in which the passage ofthe wheels over streetcar rails at an oblique angle and over otherobstructions which project above the general level of the roadway isfacilitated by placing' notches along both corners formed by the sidesand tread of the tire on each wheel. Each notch opens out into the treadand one side.

One object of the invention is to so form the notches that Withoutinterfering with the function above noted they will not make the treadnarrower than the body of the tire, eX cept just at the notches, and atthe same time have the notches inclined. The purpose of the inclinationis to enable the Wheel in rolling along the ground to lift free from mudwhich may press into the notches, and thereby reduce the liability ofthe notches becoming clogged or the throwing of mud by the notches.

Another object of the invention is to make the walls of each notch partof a semicylindrical surface, which can be cut in the tirerim by asuitably-guided drill, so that the operation of cutting the notches canbe performed on the tires without removing the wheels from 4the vehicle,and the vehicle can be kept in a condition for immediate use while thetires are being notched. This is desirable, as an important applicationof the invention is to the Wheels of fire-engines and to hose-carriages,which must be kept in a condition for immediate use while the tires arebeing notched.

In the accompanying sheet of drawings, which forms a part of thisspecification, Figure l is a perspective view of a portion of awheel-rim, showing the felly, the tire, and

2 is a perspective view of the rear portion of a hose-carriage,showingthe invention applied to the tires of the rear wheels.

The tires T of the wheels are carried by the fellies F in the usual way.The exposed parts of each of the tires are a tread t, the sides s, andthe corners c, formed by the meeting of the tread with each side. Eachnotch a intersects one of the corners and opens out into the tread andthe adjoining' side. For wheels of a fire-Vehicle l make each notchabout an inch in width and space the notches perfectly at intervals ofabout three inches along each corner. The notches are preferablyalternated on the two corners instead of being placed directly oppositeto each other. The tire therefore does not have its crosssection reducedat any point by more than the amount'relnoved in forming one notch. Thewalls of each notch form part of a semicylindrical surface, the axis ofthe cylinder being inclined to the tread of the tire at the point ofintersection at about thirty degrees. All parts of the walls aretherefore also inclined to the tread, and since they are within asemicylinder they are at all points oblique to the tread of the tire, sothat they will freely lift away from any mud which is pressed into thenotch as the wheel rolls along the ground.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

A wheel-tire having a tread the width of the body of the tire, andformed with inclined straight semicylindrical notches at the cornersformed by the sides and the tread of the tire, the ends of each notchopening out at the tread and the adjoining' side of the tire,substantially as described.
